    Amsoil in both differentials and transfer case..... 1.3mpg gain. Amsoil signature oil and I'm getting 2 mpg over stock.
    I looked, Redline, Amsoil, and Mobile1 all have full synthetics for auto trans.

    You can buy the stuff online, or I'm sure the regular parts stores (O'reilly & Autozone) have the Mobile1 fluid.

    Any other ?'s.....?

    What about the numerous people have warned against using other trans fluids besides Toyotas. Even toyota techs have said that the transmission is so finicky and to switch from factory type fluid to others usually causes problems?

    I just found that we can apply for a trial membership free for 6 months and get dealer prices. That saves 20% off the retail price of all products. Not too shabby.

    I just signed up myself. Best of all for me, there is a distribution center here in Chicago-land saving me shipping costs. I'm going to order as much stuff as I can afford in the 6 months- its noticeably cheaper than the $9 Mobil1 I've seen at the parts stores. AND you won't have to buy oil for years!

    Think about it, its synthetic, so it wont oxidize like dino-oil.

    1100 miles on the vehicle and if reports says non-Toyota ATF could cause problems, I'll still with the OEM stuff.

    Thanks for the heads-up on the abbreviations. Been reading TacomaWorld and guessing at what they meant.

    As for saving gas. Picked up a 08 PreRunner in January 13 and hit the road for over 3700 miles. Very disappointed with 17-18 mpg for the whole run. My 96 4Runner would have gotten 20-22 and maybe 24 down hill from New Mexico. Something had to be done.

    1) Replaced the factory tires with four Michelin LTX M/S2 P245/75R16 and kept the pressure right.
    2) Changed the oil to 5-30 Mobile One.
    3) Changed the air filter, just a Fram, but the next one will be one recommended by the several posters.
    4) Installed a new set of plugs.
    The above items were things done to the 96 SR5 4Runner as routine maintenance and I knew they would help.
    5) As an old time muscle car fan, I knew that a torque tube would help. It is a 3" tube from the junction behind the cats to the muffler. I selected that location so I could remove the tube if it did not help. The tube mod was less than 70$.

    Then the repeat trip. The Taco got 20 to 24 average. It took 16.3 gallons to travel from Santa Fe, to Las Vegas(NM), to Mora, to Coyote Creek, back to Las Vegas and to the filling station at Lake Side Dr and I-40 in Amarillo, TX.

    On the down side, I pulled a 22' flat bed trailer for my brother loaded with wood working machines and a tornado shelter to be tested at Texas Tech Wind Center from Dallas to Lubbock and got just over 13 mpg. Glad he paid for the gas. I had hoped for 16 to 17 mpg. On the trip back, down hill with just the shelter, we got 17.3 mpg.

    As a daily driver in DFW I get 19.3 to 20.8 mpg by driving the speed limit. Sometimes I feel like I need a slow moving vehicle triangle on the tail gate.

    Amsoil in both differentials and transfer case..... 1.3mpg gain. Amsoil signature oil and I'm getting 2 mpg over stock.
    Just to clarify, the 4x4 will see greater gains by going synthetic because of the extra differential & t-case. I'm not saying you 5 lug guys wont' see gains, just that the 6 lug people will see more of a gain by going synthetic with the additional differential and transfercase because the 4x4 is pushing that many more gears.

    I called Amsoil, and they say their ATF fluid will not void factory warranty..... I will call Toyota tomorrow to confirm. I will call all the way to corporate if I gotta.... will post as soon as I know.

    I got my reply from Amsoil.....

    the web page for drain intervals is:
    http://www.amsoil.com/lit/g1490.pdf?gear-lube

    The drain interval for ATF is the same, so I would be most interested in focusing on the manual trans& differential& transfer case for the longer life and reduced friction to realize noticeable MPG gains.

    Hi! I just joined, had my 2013 Tacoma about 2 months now. I am installing fog lights, and the wiring is giving me some problems mainly no instructions or skematics. Any one know what to do with this mess of wires?

    Hey Jimmy, :wave:

    Welcome to Tacoworld.
    You could try starting a separate thread in the 2nd gen forum. Be sure to post some pictures of your problem, and put your lighting question as the title.

    There are a lot of very knowledgeable people here and someone will have an answer. I don't know shit about car wiring, but others do. :thumbsup:

    I noticed that most people seem to agree that larger tire-diameters hurt fuel mileage, but I'm wondering how many of those folks are still going by the stock odometer to track fuel. It's true that it most likely hurts your fuel mileage for city driving, but there's a good chance that at least the taller street tires improve highway MPG, but you'll never know unless your odometer or method of miles-tracking is accurate. Otherwise, it's sure to hurt your MPG, since it looks like you're going shorter distances than you actually are.

    Just food for thought. Sorry if it's a dead horse.

    Larger diameter tires do effectively raise the final gear ratio so that the engine is turning slower at any given speed. This would favor better freeway gas mileage. But what works against better gas mileage is the heavier rotating wheel and tire weights. There's an old rule that one pound of rotating weight equals ten pounds of static weight. With different wheel diameters you also throw off your odometer reading, so that you would need to use a percentage correction factor when computing gas mileage, to adjust for the slower turning wheels.

    That's the thing. I wouldn't be surprised if half the people reporting worse MPG after the bigger wheels/tires are put on, are actually getting BETTER MPG.

    It all depends on driving conditions. I think someone who puts on mostly highway miles will likely see a net gain. The added weight is less of a factor at higher speeds, going downhill, extra weight even helps.

    Anywho, someone else's MPG doesn't really factor in to my own, but there just seemed to be a lot of universal agreement that it will suffer no matter what.

    Yes. That's entirely possible, because the odometer would register less than the actual traveled miles. I'm not sure how many people actually go through the time and trouble to change their speedometer gears when they put on big heavy large diameter off road tires.

    That's also possible, but only at a constant speed. As once a flywheel is rotating that energy needed to spin it remains stored within it as the inertial resistance to changing speed.


    The problem is stop and go driving. As it takes more energy to get those four heavy flywheels spinning. When the brakes convert that energy into heat to slow down or to stop... that energy is lost and the next acceleration also takes more energy.

    My MPG went up after going from heavy stock wheels and 245/75-15 tires up to lightweight wheels (18ish lbs) and 265/76-16 tires (about 40 lbs) simply because of the taller final gear ratio (especially on the highway while under 70) but also because I shed unsprung weight at the wheels/tires in the process. Works great when you only have about 125 horses working for you.

    I do correct for the odo difference of 11.9% and have checked that percent/new speed with gps and speed trap things. It's right on the money.

    I enjoy having oversized tires AND netting about 20% above EPA in the winter :D

    This is old, from July 25th at the most recent fill up. But my record for the Summer was last week. I got 24.25 MPG and didn't even go under the speed limit to achieve it.

    I've got the 4.0 and 6speed transmission. What is the deal with 6th being geared so low? 72mph is 2500rpm. This motor has way more power than what is necessary to maintain cruising speed at much lower rpm. I wish 6th was around 1900rpm. I have to think if it was, I'd get a lot better gas mileage over the highway.

    Any off road truck will always have lower gears.

    My 5 speed 2 wheel drive came with 3.31 street gears, so 60 mph is 2,000 and 75 mph is 2,500 rpm. But that's with the smaller 4 cylinder 2.7.

    I would think that your 4.0 would be powerful enough to push higher gearing and am surprised that the 6 speed doesn't have a wider range of ratios.

    Yea when I put on my bigger tires my mpg's didnt change much either. Did the same thing as you went from steel to aluminum wheels and calculated for the % change in tire circumference into my mpg calculations and still got pretty much stock mpg's. Gotta stay off the interstate and the go pedal to do that though. I had people call me a liar because they couldn't get close to my mileage, but I could make a 5 lug manual get 10 miles per gallon if i drove it like an asshole.
